Decidamp® SP150

Water-based Vibration Damping Compound

Decidamp® SP150 (formerly known as Soundpaint) is an advanced, water-based viscoelastic damping compound and adhesive designed to dramatically improve structural acoustics. Formulated with specialized polymer technology, it directly absorbs and dissipates vibrational energy caused by flexural stress, eliminating panel coincidence and resonance noise.

Engineered specifically for demanding environments like the marine industry, Decidamp SP150 offers exceptional fire resistance and complies with international safety codes. Its lightweight, non-toxic formula makes it ideal for interior spaces where sound control is essential for comfort and structural performance.
